查询词典 enrichment

The direct incorporation of U-13C glucose was estimated by the intensity increase of m/z to F(F was parent fragment, and n was the carbon number in the fragment), while the total isotope incorporation from the added 13C could be calculated according to the abundance ratio increment summation from m/z (Fa+1) through (Fa was the fragment containing all original skeleton carbons, and T was the carbon number in the amino acid molecule). The 13C enrichment in the target compound was expressed as atom percentage excess, and that of D-amino acid needed to be corrected by the coefficient of hydrolysis-induced racemization. The 13C enrichment reflected the carbon turnover velocity of individual amino acid enantiomers, and was powerful to investigate the dynamics of soil amino acids.

外加葡萄糖直接合成氨基酸的比例可利用质谱碎片的相对强度变化来评价（n为质谱碎片F中含有的碳原子数目）；而源于葡萄糖的13C同位素在氨基酸分子中的富集程度是所有同位素峰相对强度变化的总和。13C在目标化合物中的富集比例用原子百分超评价，D氨－基酸的APE还需进一步利用水解诱导的外消旋化系数校正。13C在目标化合物中的富集程度可反映各氨基酸手性异构体的碳循环速率大小，是研究土壤氨基酸动态变化的有力工具。

The average concentrations of Cr, Cd and Pb in ectoskeleton, liver, and muscle were 4.03, 0.12 and 12.31 μgg^(-1), 3.88, 1.04 and 9.12 μgg^(-1), and 4.16, 0.09 and 0.72 μgg^(-1), respectively. Among the three test sites, there existed significant differences in the enrichment of Cr in ectoskeleton and muscle, and of Cr, Cd and Pb in liver. The enrichment of test heavy metals had no notable correlation with the body mass of P. clarkia, and no significant difference was found in the enrichment of the heavy metals between female and male individuals.

In order to find out completely the soil-wheat contaiminated by heavy metals in Tianjin sewage farm, we collect samples on the dry land and examinate contents of heavy metals in soil-wheat system. Firstly, the anthor evaluates that soil irrigated by sewage that has been contaminated slightly, the main polluting factors are Cd and Zn, and then the anthor evaluates soil according to different regions, soil types and irrigating water. Secondly, the anthor analyzes content and enrichment ability of heavy metals in different part of wheat, evaluates wheat is contaiminated by Cd widespreadly, only few samples polluted by Zn.Finally the anthor put up correlative analysis about heavy metal contents in the soil-wheat system, as well as plant enrichment coefficient and some physico-chemical properties of soil, and establishes a prognostic model about heavy metal content among wheat spike, soil, soil types, PH, organic matter and salinity with the quantifying theory.The prognostic accuracy of primarily contaminative factors is the best with compound correlative coefficient examining, the model can be founded.With improvement of living level, people need cleaner food.

为全面了解天津市污灌区农产品生产地土壤和旱地作物小麦的重金属污染状况，我们于2004～2005年对全市污灌区的土壤和小麦进行了采样，在对该区土壤—小麦系统中六种重金属元素(Cd、Cu、Pb、Zn、Cr和Ni)的含量进行检测的基础上，本文首先分析评价了污灌区农田土壤的环境质量总体已达到了轻度污染水平，主要的污染因子是Cd和Zn，同时对污灌区农田土壤分区县、土壤类型和不同灌水类型进行了评价；然后分析了重金属在小麦不同部位的含量与富集能力，评价了污灌区旱地作物小麦普遍遭受了Cd的污染，只有个别样点遭受了Zn的污染；最后对土壤—小麦系统重金属含量间以及植物富集系数与土壤部分理化性质间进行了相关分析，由于土壤类型是定性变量，本论文以数量化理论建立了小麦穗实中重金属含量与土壤中重金属全量、土壤类型、PH值、有机质和全盐量间的预测模型，经复相关系数检验，污灌区主要的污染因子Cd和Zn的预测精度最高，模型可以成立。

Results show that Pb enrichment factors varied from 1.0～1.8 in the cultural layers, and were not quite high. However, with the history going on from the Dawenkou Culture to the Longshan Culture, the Pb enrichment factor displayed an obvious rising trend, which indicated that the Pb in the cultural layers was probably associated with the development of metallurgic activities in the middle stage of the primitive society. From 5 050 cal a BP to 4 000 cal a BP, China underwent Stone Age, Chalcolithic Age and Bronze Age in sequence. Pb dust in the atmosphere increased with intensifying utilization of copper resources, which was probably the main cause of the rising enrichment factor in the cultural layers.

但是随着时间的推移，从大汶口文化到龙山文化，Pb的富集系数有明显逐步上升的趋势，表明遗址剖面中的Pb很可能与原始社会中期发展起来的冶金活动有关。5 050～4 000 cal a BP间，中国先后经历了石器时代、铜石并用时代，到最后进入青铜时代，这个过程中铜资源利用越来越多导致产生的大气粉尘铅越来越多，很可能是YC1剖面中Pb富集系数逐步增长的主要原因。

Since they are now beginning to consider the necessity of technical manpower dispatching, the selection of the right temporary help service firms has become a very important issue.In the past, supplier evaluation and selection studies mostly focused on the manufacturing and service industries. Hence, this paper studied the past domestic studies conducted on supplier selection to understand the appropriate selection guidelines that would serve as the fundamental guidelines for the selection of outsourcing manpower companies. The PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluations) proposed by Brans and Vincke in 1985 was used as the supplier selection tool for the study. Finally, we employed a simulated case study where we consolidated the selection guidelines,method and tools to create a reference for future practical applications and academic researches.

在过去，有关于厂商评选的国内外文献中，其研究对象以制造业及服务业居多，针对人力派遣公司评选准则之文献则相当的缺乏，因此，本研究将讨论国内半导体设备供应商评选技术人力派遣公司之准则，藉由过去国内学者对供应商评选之相关研究，寻得适宜的评选准则，以做为评选人力派遣公司之基础，采用由Brans及Vincke在1985年所提出之PROMETHEE（Preference Ranking Organization Method for Enrichment Evaluations）法做为评选供应商之工具，并将此方法藉由Excel应用软体予以辅助计算，最后，使用模拟个案，将研究所提出的评选准则、方法及工具三者结合，提供实务运作及学术研究上作为参考。
